Men
like it when women let them know that they're happy. That much is not
surprising, but what is remarkable is that the reverse is actually not
true.

According to research by psychologist Shiri
Cohen at Massachusetts General Hospital, women like it best when men
share their anger and frustration:

"The women tend to want to engage around conflict," she
told Shots. "They're deriving more satisfaction when they see that
their partner is upset."

Evidently we women see a man's willingness to share negative feelings
as a sign that he's invested in the relationship. Cohen says: "That's
telling her something about his availability to engage in the conflict."

Men feel exactly the opposite about those moments of conflict:
They see it as a threat to the relationship. Instead, Cohen says, "They
do derive satisfaction when their girlfriends or wives are happy."
